安装oracle软件后，必须要先配置listener才能dbca建库，但是netca却报下面的错误。
Oracle Net Services Configuration:## An unexpected error has been detected by HotSpot VirtualMachine:## SIGSEGV (0xb) at pc=0xa4bf5f4e, pid=11819, tid=3086902976## Java VM: Java HotSpot(TM) Client VM (1.5.0_17-b02 mixedmode)# Problematic frame:# C [libclntsh.so.11.1+0x421f4e] snlinGetAddrInfo+0x1b2## An error report file with more information is saved ashs_err_pid11819.log## If you would like to submit a bug report, please visit:# http://java.sun.com/webapps/bugreport/crash.jsp#/u01/oracle/bin/netca: line 178: 11819Aborted $JRE $JRE_OPTIONS -classpath $CLASSPATH oracle.net.ca.NetCA $*
是由于默认的主机名导致的，修改2处
[oracle@jc11g ~]$ cat/etc/sysconfig/networkNETWORKING=yesHOSTNAME=test11gGATEWAY=192.168.1.254
[oracle@jc11g ~]$ cat /etc/hosts# Do not remove the following line, or various programs# that require network functionality will fail.127.0.0.1 localhost.localdomain localhost test11g
再执行
hostname test11g
让oracle用户退出重新登录就可以正常启动netca了
